@cmpdmio83 services subscribed to directly with the provider can be accessed on any device. We can access Disney+ on Roku, Android, or other devices. Same with HBO Max, as both are subscribed directly with the provider.
Services subscribed to through a 3rd party often have restrictions on how that service can be accessed. If you subscribe to something through Roku, it can only be accessed on Roku devices. If you subscribe to something through Amazon (on the Fire device), you are only going to be able to access that subscription through Amazon. Sometimes that service can be accessed on other devices through the Prime Video app, and sometimes it can only be accessed on an Amazon device (Fire TV or tablet). That is common throughout the industry, and not something specific to Roku, Amazon, or any other provider.
